Do yourself a favor and check out the Super Tigre G2300. I was shocked at the speed of this plane and engine combo. Though the Super Tigre can be a bit tedious to setup and break in initially, the cost of the engine over shadows the time and patience needed to bring the motor to life. I like the Fox Miracle plugs in the ST 2300 and if you are setup with glow driver, just make sure you set the engine at proper height to tank.
